  1. Overview • Antibiotic resistance – a global issue • The link between antibiotic use and resistance • Addressing antibiotic resistance • The role of antimicrobial stewardship • Actions for Antibiotic Awareness Week • 7 ways to improve antibiotic use Wherever they are used, antibiotics must be used responsibly

  2. The “miracle” of antibiotics • Discovery of penicillin revolutionised treatment of infectious disease • Increased life expectancy due to ability to prevent and treat infection Crude mortality rates for all causes, non infectious causes and infectious diseases over the period 1900-1996. 1. Armstrong GL et al, JAMA 1999;281(1):61-66

  3. “Anne Miller, 90, first patient who was saved by penicillin” In 1999, the New York Times published an article about Anne Sheafe Miller…. “…who made medical history as the first patient ever saved by penicillin…died on May 27 in Salisbury, Conn. She was 90…..” • March 1942 - Mrs Miller was near death, suffering from a streptococcal infection. Doctors had tried everything available (sulfa drugs, blood transfusions, surgery). All treatments failed. • Desperate, doctors obtained a tiny amount of what was still an obscure, experimental drug and injected Mrs Miller with it. • Her hospital chart (now an exhibit at the Smithsonian Institution), registered a sharp overnight drop in temperature, and by the next day she was rapidly recovering. Mrs Miller's life was saved by antibiotics. • Penicillin also saved the lives of all those previously felled by bacterial infections with streptococci, staphylococci and pneumococci, and the lives of an untold number of servicemen and civilians wounded in World War II. 2. Saxon W, New York Times, June 9, 1999

  4. Antibiotics continue to save lives,every day… • Ability to control infection is critical to other advances in medicine • Neonatal care • Transplantation • Chemotherapy • Immunosuppression • Complex and routine surgery • Obstetric care • Intensive care interventions

  5. But…….Antibiotics are a limited resource We have….. • Growing rates of resistance • Increased use of antibiotics • Decreasing pipeline of new antibiotics 3. Spellberg, B. et al. Clinical Infectious Diseases 2008; 46 (2):155-64

  6. Emergence of antibiotic resistance “It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body.” Sir Alexander Fleming, 1945 The issue of antibiotic resistance was recognised early in the ‘antibiotic era’. It threatens our ability to control infection. 4. Sir Alexander Fleming, Nobel Lecture, December 1945

  7. Emergence of antibiotic resistance Antibiotic resistance threatens ability to control infection 5. Pray LA Insight Pharma Reports 2008, in Looke D ‘The Real Threat of Antibiotic Resistance’ 2012

  8. Resistance spreads rapidly 6. Centers for Disease Control and Prevention http://www.cdc.gov/hai/

  9. Impact of resistance • Increased morbidity/ mortality • Evidence across many pathogens • Untreatable infections • Now being encountered • Increased costs9 • $18-29,000 US/patient • Excess length of stay 6.4 – 12.7 days/patient Real people are affected 7. IDSA ‘Patient stories’ 2013 http://www.idsociety.org/Patient_Stories/ 8. Roberts RR et al. Clinical Infectious Diseases 2009; 49:1175-1184

  10. AMR is a problem globally…… Key findings: • Very high rates of resistance observed for common bacteria that cause common health care associated and community acquired infections (for example urinary tract, pneumonia) in all WHO regions • Significant gaps in surveillance • Urgent need to strengthen collaboration on global surveillance as the foundation of global strategies to address AMR. 9. World Health Organization 2014 Antimicrobial Resistance: Global Report on surveillance. http://www.who.int/drugresistance/documents/surveillancereport/en/ Last accessed 21/9/14

  11. ……a problem in our region….. Korea ECOL: 37% KPNE: 40% China* ECOL: 54% KPNE: 41% Japan† ECOL: 17% KPNE: 11% HongKong ECOL: 46% KPNE: 23% Taiwan ECOL: 91% KPNE: 75% India ECOL: 78% KPNE: 64% Thailand* ECOL: 55% KPNE: 50% Philippines ECOL: 47% KPNE: 23% Singapore ECOL: 21% KPNE: 32% Malaysia ECOL: 36% KPNE: 45% Indonesia ECOL: 71% KPNE: 64% Australia ECOL: 12% KPNE: 15% Resistance (%ESBL) in the Asia Pacific region NewZealand ECOL: 11% KPNE: 10% 10.

  12. ….and a problem here in Australia We need to act now!! 13. Turnidge J et al. MJA 2009: 191(7): 368-373 14. LookeDF, Gottlieb T, Jones CA, Paterson DL Med J Aust. 2013 Mar 18;198(5):243-4.

  13. Antibiotic resistance: in our health service • Which infections are we seeing ? • What are our susceptibility and resistance patterns ? • [Insert hospital data] • [Numbers of cases] • [Examples of cases]

  14. The link between antibiotic use and antibiotic resistance Countries with high penicillin consumption also have high rates of penicillin resistance in pneumococci Occurrence of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) versus outpatient use of penicillins in 17 European countries.  15. van de Sande-Bruinsma N et al. Emerging Infectious Diseases 2008; 14(11):1722-1730

  15. Antibiotic usage varies between hospitals National Antimicrobial Utilisation Surveillance Program (NAUSP) 2013-14 annual report14 16. South Australian Infection Control Service. National Antimicrobial Utilisation Surveillance Program (NAUSP) 2013-14 Annual Report. Even within a county there is inter-hospital variation in antibiotic consumption e.g. Meropenem use – 10-fold variation across 64 Australian hospitals

  16. Adding to the problem ….Antibiotics are a limited resource The dwindling development of antibiotics…Number of US FDA Antibiotic approvals18 • Few new antibiotics • Majority developed pre 1970 • 3 new classes in 20 years Global recognition that: • new antibiotics are urgently required • we need to conserve what we have 19 17: Adapted from Spellberg B et al. The epidemic of antibiotic resistant infections: A call to action for the medical community from the Infectious Diseases Society of America. ClinInf Dis 2008;48:155-64 18.

  17. A great deal of antibiotic use is inappropriate There is evidence to suggest that 25 - 50% of antibiotic prescribing in Australian Hospitals is inappropriate19 This includes; • Unnecessary prescription of antibiotics, such as for viral infections (colds) or for prolonged prophylaxis • Using broad-spectrum antibiotics (such as third generation cephalosporins, carbapenems) when narrow-spectrum antibiotics are effective • Prescribing too low or too high a dose of antibiotic • Continuing treatment for longer than necessary • Not prescribing according to microbiology results • Omitting doses or delayed administration • 19 . Duguid M and Cruickshank M. Antimicrobial Stewardship in Australian Hospitals . 2011

  18. Antibiotic usage in our health service Insert local usage data if available Include information about local participation in the National Antimicrobial Prescribing Survey 2013/14 if participating, insert relevant results

  19. What can be done to address antimicrobial and antibiotic resistance ? Two complementary arms Infection prevention and control Antimicrobial stewardship

  20. Addressing Antibiotic Resistance in our health service. • Infection prevention and control • Hand hygiene • Standard and transmission based precautions • Environmental cleaning • Aseptic technique • Workforce immunisation • Antimicrobial stewardship

  21. NSQHS Standards, Standard 3: Antimicrobial Stewardship Criterion 20. National Safety & Quality Health Service Standards .Access at www.safetyandquality.gov.au/our-work/accreditation/nsqhss/

  22. Antimicrobial stewardship (AMS)Optimising use of antibiotics • Aim to: • Maximise best outcomes • Minimise harm to the individual • Minimise ecologic harm to wider community • Requires team work at all levels: • Executive and clinical leadership • The clinical team (doctors, nurses, pharmacists, allied health) • Consumers

  23. Antimicrobial stewardship (AMS) • an inter-professional effort, across the continuum of care • timely and optimal selection, dose and duration of an antimicrobial • promotes best clinical outcome for the treatment or prevention of infection • minimal toxicity to the patient • minimal impact on resistance and other adverse events

  24. Essential strategies for effectiveAMS

  25. Antimicrobial Stewardship in our Hospital • Local processes for stewardship • Include local processes for seeking ID/micro consults and pharmacy advice, guideline and formulary information, contacts, any other relevant information.

  26. Our Health service tools and activities to promote appropriate use of antibiotics AMS committee (or other committee e.g. infection control, drug & therapeutics committees) to coordinate activity Education prescribing guidelines Policy Formulary with restrictions and approval Access to expert prescribing advice ID, Micro, Pharmacy Audit and feedback Who to contact?

They are important movers, shakers, and front-line players, especially in this age of social media”. 23. Dr Margaret Chan, Keynote address at the conference on Combating antimicrobial resistance: time for action Copenhagen, Denmark 14 March 2012 .http://www.who.int/dg/speeches/2012/amr_20120314/en/last accessed 22/9/14 Monday 17 November Australian Antibiotic Awareness Week #ABXAus Tuesday 18 November #AntibioticDay A global twitter chat involving partner countries Organisations and experts participating

  34. Remember…. Antibiotics are a limited, precious resource Antibiotic resistance is a growing, global problem Antibiotic resistance is an issue in our hospitals and in our communities, for all of us who prescribe or use antibiotics Resistant infections are harder to treat and are associated with higher rates of mortality and morbidity Inappropriate use of antibiotics promotes resistance Few new antibiotics are being made available To conserve the antibiotics we have, antibiotics must always be used responsibly If we don’t all take action today ……. there may be no cure tomorrow…
